The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the Grafton - Tenterfield, NSW, 2011 survey were acquired in 2011 by the NSW Government, and consisted of 100488 line-kilometres of data at 250m line spacing and 60m terrain clearance.
